摘要
通常情况下,视频会议系统终端会场的会议室只有一个,视音频输入信号也不会超过两个。但有的视频会议终端会场,由于各种原因其输入视音频信号可能超过两个而出现三个以上,或者需要两个或三个同等功能的会议室。对于以上需求,可以通过增加视频编解码器、视音频及控制选择器或者视音频矩阵等方法加以解决。
General speaking, the council chamber for the video conference terminal is only one and with less than 2 cameras in the room. However, some times, there are two or three council chambers while probably more than 2 cameras in a room. There are three methods in solving these problems. The first is to use multiple codee, the second is to use the switch of AV and control, and the last is to use the AV matrix.
